Research applications
IGF-1 LR3 (Long R3 IGF-1) is a recombinant 83-residue analog of human insulin-like growth factor-1 with an arginine-for-glutamate substitution at position 3 and a 13-residue N-terminal extension, reducing IGFBP binding and extending half-life. It is used in IGF-1 receptor and PI3K/Akt/MAPK signaling research, and cell-proliferation and differentiation models.
